100
Covalent bonds involve this relationship between valence electrons.
What is sharing?
100
This is the positively charged subatomic particle in the nucleus.
What is a proton?
100
Compared to ionic compounds, covalent compounds had a higher/lower/same melting point.
What is lower? (They melted sooner)

What is 8?
200
Pick the one that is NOT a covalent compound: H2O, Cl2, MgS.
What is MgS?
200
This forms when an atom gains or loses electron(s) to become stable.
